CARI-COUPLING.

SPECIFICATION forming part of Letters Patent No. 608,056, dated July 26,1898. Application filed March 7, 1898. Serial No. 672,932. (No model.)

T0 at whom, it may concern.-

Be it known that we, HERMFJNEGILDE Lor- SELLE and AIME LoIsELLE, of thecity of Winnipeg, Manitoba Canada, have invented a new and usefulImprovement in Oar-Couplings, of which the following is aspecification.

The object of our invention is to provide a simple, cheap, and effectivecar coupling which shall couple the cars automatically when they cometogether, which will not come apart accidentally nor cramp and bind inturning curves, and which may be adapted also to coupling with carshaving the ordinary construction of draw-bar and the ordinarylink-and-pin coupling. 7

It consists in the peculiar construction and arrangement of thedraw-heads, couplingjaws, and means for operating them, as will behereinafter more fully described, and pointed out in the claims.

Figure 1 is a side elevation of the two drawbars with parts of the carsustaining the same, the draw-bars being disconnected and one of thembroken away in section to show the means for coupling with cars havingthe or-" dinary form of draw-bar. Fig. 2 is a plan view of the twodraw-bars coupled. Fig. 3 is a perspective detail of one of thecouplingjaws, and Fig. 4 a similar view of one of the special forms oflinks for coupling with ordinary draw-bars.

In the drawings, A. represents one of our improved draw-bars. This mayhave the usual connection with the timbers of the car to adapt it toeither freight or passenger cars and is made with a hollow metal headhaving an open front and top. In the back end of this hollow head, nearthe top, there is hinged upon a horizontal bolt 1) a vertically-swingingjaw B. This jaw has an elongated barrel 1), which envelope thehorizontal bolt b and has a perforated lug b at the top, by which it islifted, and its front end is turned inwardly at- Z) to form agrappling-hook. This hook is on its inner face formed into corrugatedsurfaces which intermesh or fit into similar corrugated surfaces on theface of the jaw of the other draw-bar, while the outer face of thesehooks are made tapered or wedge shaped, so that when the twograppling-hooks of the opposite draw-bars come together one will ride upover the other and, dropping behind, will have its corrugationsinterlocked with those of the other face. This makes a positiveconnection of the two hook-shaped jaws, but gives sufiicient play, sothat they do not cramp and bind in turning curves.

The two draw-bars of our car-coupler couple automatically when they cometogether, so as to avoid all danger involved in going between the carsand are disconnected or uncoupled by hand either from the side or top ofthe car as follows: C is a rock-shaft journaled in bearingson the sidesof the car and having a cranked portion 0 in the middle, which isconnected by short rods or links 0 with the perforated lug on top of thehook-shaped jaws. These rock shafts are provided at their ends withcrank-arms n or hand-Wheels, by turning which either jaw may be raisedabout its horizontal center bolt, so as to be lifted above and out ofengagement with the other jaw. To operate this rook-shaft from the topof the car, a rod M extends upwardly to the top of the car and is thereconnected to an elbow-lever L.

To enable our draw-bars to couple with those ordinarily in use employinga link-andpin connection, we form the draw-bar with a lower chamber orthroat in the thickened same is formed also a vertical pin-hole d. Inthis throat there is arranged a special form of link E,-(see Fig. 4,)made of a rod of iron bent into a loop shape at one end and at the otherhaving one end bent around the shank of the other in the form of an eye,while the other and longer end is extended at right angles to' the bodyof the link and formed into a handle 6, which projects outside of thedraw-bar and by which the link may be "handled from the side of the carwithout going between the cars. This link embraces a coupling-pin p inour draw-bar and may be protruded by the handle far enough to receivethe coupling-pin of an ordinary draw-bar, as shown in Figil, or be drawnback into its throat and out of the way.

To prevent the accumulation of snow, rain, or dirt in the head of thedraw-bar, a taper ing bottom is formed with a discharge-hole h in thecenter.

In defining our invention with greater clearness we would state that weare aware "lower lip D of the draw-bar, and through the r more heavilythan the next or when the carspass over uneven rails or a roughroad-bed. To prevent the separation in vertical direction is the objectof the corrugation on the adjacent faces of the coupling-jaws, and saidcorrugations are made in a peculiar way, as follows: Referring to Fig.3, each jaw has in the middle a recess with a lip at top and bottom ofthe recess, and just beside this recess is a lug partially closing theend of the recess and having a notch at the top and bottom of the lug.Two corrugated jaws of this character intermesh perfectly and lockagainst vertical as Well as sidewise motion.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. In a car-coupling the combination of a draw-bar having a hollowcoupling-head, open at the top and front end and having a drainage-holein the bottom, and two coupling-jaws hinged at their rear ends uponhorizontal axes and having their front ends made with tapered noses eachprovided on its inner grappling-face with a central recess having a lipat top and bottom of the same, and also a lug partly closing one end ofthe recess and having a notch above and below the lug substantially asand for the purpose described.

2. A car-coupling having a pair of jaws pivoted 011 horizontal axes andhaving tapered noses and grappling-faces, each face having a centralrecess with a lip at top and bottom of the same, and a lug partlyclosing one end of the recess and having a notch at the top and bottomof the lug substantially as and for the purpose described.
